This is a good question and the answer all depends what your biggest concern is! Kybella is a great treatment for submental fat, but will do nothing for jowls and neck tightening. More than likely you will need more than one treatment of Kybella to achieve your desired results. Morpheus is a great treatment for all of the things you are looking to treatment. The combination of micro needling with radiofrequency helps to resurface and remodel the skins structure. The puncture caused by the micro needling helps to boost new cell growth and stimulate collagen while the penetration of heat from the radiofrequency helps to contour and smooth the treated area. It is recommended to have 3 treatments at 4 weeks intervals for maximum results. It would be best to find a provider in your area that offers both and schedule a consult with them. Both of these options can be explored and the best recommendation would be given by whoever examines you. Good Luck!
